Belts keep a car running smoothly by carrying power from the engine to other parts of the vehicle. A broken car belt can create any number of issues, from loud noises to an inability to start the vehicle, so any suspected problems should be promptly checked out by an auto repair professional. To help you better understand these crucial components, the three most common types of belts are discussed in more detail.

A Guide to Car Belts

1. Serpentine Belts

Serpentine belts are perhaps the most well-known of all belts as they are a part of virtually all cars manufactured in the last 30 years. They loop throughout the engine and power its various parts, such as the alternator, power steering, and air conditioner compressor.

A broken serpentine belt often emits a loud screeching sound, and they may exhibit physical signs of damage, like visible cracks or deep grooves around the belt itself. Given their important role in powering multiple parts of a vehicle, a broken serpentine belt can result in a breakdown or a car that won't start; however, they can easily be fixed by an auto repair shop.

2. Timing Belts

A timing belt links the crankshaft and camshaft, two essential parts of the internal combustion engine that ensure the efficient transfer of energy. The belt helps these two parts works in unison. If a timing belt breaks, the car will not start. In some cases, there may be signs that a timing belt is wearing down; red flags to watch out for include a rough or jolting idling of the engine, engine misfires, or smoke coming from under the hood of the vehicle.

3. Drive Belts

Drive belts, also called V-belts, are often found in older vehicles. They start in the crankshaft and transmit power to other parts of the engine. They typically only power one or two parts, so it's not uncommon for a vehicle to have several drive belts. Depending on the parts they're powering, broken drive belts don't always result in a total engine failure; for instance, the belt for the air conditioner compressor may only result in an AC that won't cool. If you suspect a broken drive belt, have it promptly addressed by an auto repair professional; these belts tend to wear out all at the same time.
